摘要/Abstract

摘要： 邓恩桉是一种优良速生、较耐寒的纸浆材、实木用材树种。但是,它不仅无性繁殖比较困难,而且在我国很多地区不能开花结实,广西、湖南等地13年生的种子园仍不能生产种子,目前全国造林用的邓恩桉种子都完全依赖进口,增加了造林成本,限制了它在我国的发展。试验设计采用完全随机区组设计,参试邓恩桉种源15个,107个家系。根据该试验11个月生时的高生长量,初选出优良家系30个(其中排在前10位的是52、29、35、87、94、104、86、90、76、101),平均树高2.17m;优良种源5个,它们是17915、17909、17911、18758、18264,平均树高2.39m。此试验将为营建邓恩桉实生种子园提供初步依据。

Abstract: E.Dunnii is a fast growing and cold-tolerant speciesand its wood can be used for pulpwood and sawn timber. It is a species that is difficult for clonal propagation, but has also no blooming and fruit setting in many regions of Chinaand even 13-year old seed trees in orchards in Guangxi and Hunan have not produced seed. By now E.Dunnii seed must be imported with high costs, which haslimitedits development in China. 107 families of 15 provenances have been arranged inrandomly chosen block design. 30 families are selected primitively following the longitudinal growth of 11-months old, 52, 29, 35, 87, 94, 104, 86, 90, 76 and 101 are at the front of the 30 families ranking, and their average tree height is 2.17 meters. There are five elite provenances, namely17915, 17909. 17911, 17914 and 18758, their average tree height is 2.39 meters. The result of this experiment has provided the preliminary basis for the establishment of E.Dunnii seed orchard.
